Black and Copper exhaust wrap installation instructions

  1. Determine the length of each tube by measuring from the exhaust port flange to the collector (see chart for material required). IMPORTANT- For each and every bend, add 8” more to overall length of material before cutting.
  2. CAREFULLY cut material for each tube and collector.
  3. Wrap material around the top of the first exhaust port flange and secure with Snap Strap or a hose clamp. Wrap tight, neatly and overlap 1/4". Complete all tubes and collector. NOTE: WHEN TUBES ARE, CLOSE FOR EASY WRAPPING USE A FLAT BLADE SCREWDRIVER TO SEPARATE TUBES ENOUGH TO ALLOW MATERIAL TO SLIDE THROUGH.
  4. Apply Thermo-Tec's Hi-Heat Coating. The coating increases the life of the material, changes the color and seals the pores allowing less penetration of liquids. (1) can covers 50' of material. DO NOT USE HI-PRESSURE WASH ON MATERIAL! Use a common garden hose without nozzle attachment.


CAUTION: Motor Homes/Towing Vehicles wrap 20" of primary, do not wrap collector. Do not start engine unless in a well ventilated area. Due to processing procedure, very small amounts of oil and residue will cause material to smoke up to 30 minutes until material is cured. Tape should not smoke again after cured. Due to fiberglass like nature of this material, it may cause a slight skin irritation.


RACERS INFO: Because the carburetor is receiving additional vacuum, in many cases, stepping down 1 to 2 steps in the secondary and primary jets may be necessary. Read plugs and adjust accordingly.
